That developer edition git-stable iso technically doesn’t have 5.13 but I guess 5.12.90 is close enough… but hey, looks and works as expected!
Noted that in fonts the word “Adjust all” was spelt as “djust all”; capital A was invisible
Couldn’t use plasma vaults… complained of some older fuse version (_9.9?)

[Also, would be helpful to have the fix release of libinput; the current version (at least with 18.04) has problems with some touchpad keyboard combos; this is NOT the case currently with the 16.04 version]
